YAGO - Semantic Knowledge Base

YAGO2s is a huge semantic knowledge base, derived from Wikipedia WordNet and GeoNames. Currently, YAGO2s has knowledge of more than 10 million entities (like persons, organizations, cities, etc.) and contains more than 120 million facts about these entities. YAGO is special in several ways: 1) The accuracy of YAGO has been manually evaluated, proving a confirmed accuracy of 95%. Every relation is annotated with its confidence value; 2) YAGO combines the clean taxonomy of WordNet with the richness of the Wikipedia category system, assigning the entities to more than 350,000 classes; 3) YAGO is an ontology that is anchored in time and space. YAGO attaches a temporal dimension and a spacial dimension to many of its facts and entities; and 4) In addition to a taxonomy, YAGO has thematic domains such as "music" or "science" from WordNet Domains. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog. This will be added to Knowledge Discovery Subject Tracer™.
